  1. Camera auto framing

    thanks for the reply, sorry for the silly question, but can you explain it a bit further ? so where and how are you using it ? -//edit NVM, its workign now. thank you
  2. Camera auto framing

    Hello, I am currently trying to build a asset turntable tool, most things are fine, but now i am looking for a way to automatically move the camera for and back in z to make sure, that the framing of the object is good (not too far away and not too close to avoid any clipping). The camera has no rotation. using the center of the bounding box of my asset as y position and the focal length is also fixed. whats the best approach to calculate the distance in z ? thank you for the help!
  3. triplaner inside of PointVop

    i found a way to do it. just blending 3 different planar uv projects with the help of 3 dot products. works quite nice. a few small tweaks and then i will share it here, in case someone has the same question
  4. triplaner inside of PointVop

    no, unfortunatly not. but thank you for the reply looking for a way, to transfer the same approach out of the shading context to a PointVop. i needed to create a displaced geometry for further modifactions or for example as a ground for scattering. if i do it on render time, the polygons dont match the render results. so it am mostly looking for a way to create this rgb mask inside of a vop or a wrangle to blend different maps inside of the point vop.
  5. triplaner inside of PointVop

    Hello everyone, I am looking for a way to use a tri planar projection inside of pointVop. is there a quick way or did someone build it already ? Trying to displace geo based on maps but have to export it as geo and not just on rendertime. Found someone on reddit with the same question and a solution, but i am not really getting it. still at the basics of wrangle and dot products xD Someone here, that could help me out ? at the moment i am just creating different planar uvs set (top, side, front) and planning to blend it based on the uv borders, but that probably only works on simple shapes.
  6. Wireframe and UV Distortion with mantra

    perfect, looks good as a start, thank. only proplem of this approach is the inconsistent thickness of the lines. but should work for now!
  7. Hello, i am trying to render a wireframe of the topology straight from mantra. Feely a bit stupid, but it seems way more complicated then i thought. I read about wren or creating a "wireframe-geo", but in my case, i need it from mantra as an additional image plane (via bind export). Trying to create a mantra beauty render of an asset as kind of Model QC, so besides the wireframe it would be great to also include the uv distortion (as in maya) in my render, to see if the uvs are strechted or compressed. most important is the wireframe, would be great, if somebody could point me in the right direction. Cheers, Daniel
  8. adding metadata to exr

    we did, aroud 40 days ago but still no response from side effects
  9. adding metadata to exr

    sorry, jon, was to busy to answer you. your script works perfect and excactly what i wanted. had a similiar approach but missed something, i guess. the only odd thing is, that it only works in houdini 14 and not in any houdini 15 version, maybe some kind of bug
  10. adding metadata to exr

    Hey there, first odforce post and of course a question. i am currently looking for an option to add costum meta data to my render output (exr file). to be more specifiy, i want to save the focal length of my render cam to the meta data of my exr to read them later on in nuke. all ready found a way to put it in the comments, but would be cleaner to have it as costume data. i even found the vm_image_exr_attributes, but it seems like its not working (or i am using it wrong). would be great to get some help. cheers
